Description
Technical field
The present invention relates to a kind of pivoting support of construction steel structure node, particularly a kind of universal spherical hinged support.
Background technology
Chang Yong pivoting support in the market, has following defective, perhaps can not bear very big pulling force or can not well rotate, be difficult to satisfy the actual needs of engineering, similar bearing on the overseas market is as the bearing that International airport, San Francisco adopts, complex structure, requirement on machining accuracy is very high, and price is equivalent to domestic ten times.Structural calculation shows, bearing stressed very complicated under each operating mode not only bears pressure, under some operating mode, will bear very big side-thrust and very big pulling force.This just needs a kind of pivoting support, should satisfy the requirement of these operating modes, also wants simultaneously and can well rotate, to satisfy the complete hinged condition of computation model.
Summary of the invention
The purpose of this invention is to provide a kind of steel structure universal spherical hinged support, solve that bearing and gusset plate manufacture difficulty are big, processed complex, the technical problem that involves great expense; It is weak and be subjected to behind upper pulling force the problem that can't rotate simultaneously also to solve existing steel structure gimbal anti-pulling ability.
For achieving the above object, the present invention adopts following technical scheme:
This steel structure universal spherical hinged support, wrapping shape under being by base and upper node flexibly connects, it is characterized in that: described base is the symmetrical halves pin-connected panel, its edge distribution has a circle bolt hole, in base central authorities one spherical convex surface is arranged, the hoop plate of one circle to central arc-shaped bend arranged between the bolt hole of base and spherical crown convex surface, at the lateral surface of hoop plate to the edge of base, stretch out a wing plate every 90 °, the wing plate all is higher than the hoop plate, be distributed with connecting hole on the plate face, the two halves base be assemblied into an integral body by bolt.
The middle part of upper node is the node post, top is connected with bearing sheet, and the bottom is round weight shape, and the intrados of hoop plate encases the circle stone roller of upper node, there is the concave surface of corresponding surface in the bottom surface central authorities of circle stone roller with respect to the position of the spherical convex surface of base, and the degree of depth of its concave surface is less than the height of spherical convex surface.
Be shaped as octagon, regular hexagon or square after the assembly unit of above-mentioned base.
The intrados that the circle stone roller of above-mentioned upper node is gone up cambered surface and hoop plate is slightly larger than 1/4 circular arc.
The circle stone roller periphery of above-mentioned upper node is a cambered surface, and circle stone roller middle part is upright round platform, and the boundary line of cambered surface and round platform is one to enclose the inner corner trim ditch less than 90 °.
The cross section of the node post of upper node is circle, ellipse or cross rib shape.
Compared with prior art the present invention has following characteristics and beneficial effect:
1) bearing rigidity is very big, under big tension, can freely rotate.Can bear very big pulling force, can well rotate again.For example the bearing horizontal thrust of certain engineering reaches 3650KN, vertical pulling force: 400KN, vertical pressure 3000KN, corner: 7 °, similar bearing is difficult to reach requirement, behind mechanical analysis and verification experimental verification, find bearing under very big load action, be out of shape lessly, satisfy requirement of strength.The chamfering that is provided with between bearing outer shroud baffle plate and the bearing base (being equivalent to strengthen the profile height of bearing baffle plate root) has improved bearing rigidity and intensity greatly.Bearing experimental study is subsequently also verified.Test shows that bearing not only rigidity is big, the bearing capacity height, and also the safe rotational angle under very big tension has reached designing requirement.
2) fabrication and installation are convenient, safe, cheap, can design the type of different sizes and the product of different tonnages as required.All manufacturing process is actually a casting process, and the control of castings material is with reference to DIN DIN17182.The installation of bearing also is very convenient, this is because the structure of bearing is very simple, is to be made of base and bearing annular cover plate two parts, and annular cover plate is optimized to the hemispherical plate of two make-ups, during installation, only need that the lobe female cap plate of upper node and bearing is pieced together good back rotating clutch and get final product.The bearing volume is little, and is in light weight, manually can operate with interior bearing for 300 tons, greatly reduces installation cost, improved efficient.Can reserve enough anchor hole positions in addition on the base,, improve the degree of safety of bearing so that crab-bolt is installed.
3) have good anti-seismic performance and resisting temperature deformability.The bead at this bearing base middle part has the function that the horizontal movement of structure is converted into vertical motion, thereby has weakened the water geological process effect of structure.Under big load action, bearing still is in the linear elasticity state, has very big free rotational angle, and bigger anti-shear ability is arranged, and anti-seismic performance is good, meets design requirement.
